Fig. 2: Electroadhesion of QDM gel-strip to Alg tube.
From: Reversible electroadhesion of hydrogels to animal tissues for suture-less repair of cuts or tears
a The gel and tube are contacted with graphite electrodes, with the positive electrode touching the cationic QDM gel and the negative electrode touching the anionic Alg tube. b Upon applying 10 V of DC for 10 s, the gel gets tightly adhered to the tube and conforms to the tube shape. In cases where a puncture is made in the tube wall, adhesion of the gel over the puncture location serves to patch up the puncture (see next figure).
